Manager.
Once an update becomes available, you can load it immediately or postpone installation
for up to 12 hours. After 12 hours, the update installs automatically.

low. Plug your mobile hotspot into your wall charger, and then tap Begin. (This
ensures the update will complete without the device shutting off midway.)
